LLWNL LUDA CIZEK, 0F DETROIT, MICHIGAN.

NON-CAPSIZING LIFEBOA'I.

Application filed May 22, 1919.

To all whom it may concern Be it known that I, LUDA CIZEK, a citizen of Cze-cho-Slovakia, residing at Detroit, in the county of WVayne and State of Michigan, have invented certain new and useful Im- T piovements 1n hon-(Japslliing Lifeboats, 01 which the following is a specification.

The primary object of the invention is the provision of a life boat simple in construction and light in weight readily mounted upon the deck of a vessel for easy launching upon the water whenever desired, simultaneously operable outrigger and keel members being provided for the boat, preventing the same from tipping and capsizing when in use.

A further object of the invention is to provide a life boat with outrigger and keel members adapted for positioning substantially out of the way when the boat is not in use and for ready adjustment to their operative positions when the boat is placed in the water.

A still further object of the invention is to provide adjustable outrigger and keel members connected together for assuming their operative positions when desired, automatic means being provided for maintaining the same in position for use, the structure being simple and easy and inexpensive to manufacture, as well as providing oildispensing means when found desirable.

With these general objects in view, the invention consists in the novel combination and arrangement of parts hereinafter fully described, in connection with the accompanying drawings and in which like reference characters designate corresponding parts throughout the several views.

In the drawings,

Figure 1 is a top plan view of my invention,

Fig. 2 is a vertical transverse sectional view thereof,

Fig. 3 is an enlarged vertical sectional view through one half of the boat with the outrigger shown folded, and the adjacent keel member indicated by dotted lines, the position of both keel members being indicated in their connected open positions,

Fig. at is a fragmentary longitudinal sectional View thereof,

Fig. 5 is an enlarged horizontal sectional view showing one of the outrigger connectors';

Serial No. 298,911.

Fig. 6 is an enlarged detail view of the hinge lock employed vertical and Fig. 7 is a transverse sectional view taken upon line V II-VII of Fig. 6.

Referring more in detail to the drawings, my invention comprises a boat having a hull 10 similar in shape to a canoe, longitudinal recesses 11 in the opposite sides thereof being adapted for the reception of elongated outriggers or float-s 12 at the opposite sides of the boat.

A plurality of connectors each consisting of two sections 13 and 1% connected by a hinge 15 are provided between each outrigger 12 and the adjacent side portion 16 of the hull 10 forming the inner wall of the recess 11. The outer ends of the con net-tor sections 13 are pivoted as at 17 to the adjacent outrigger 12 while the inner ends of the sections 11 are pivoted as at 18, to said walls 16. The hinges 15 are operable for folding the connector sections 13 and 14 upon each other permitting the outrigger 12 to be moved outwardly and inwardly of th adjacent recess 11 while maintaining parallel relations between the outrigger 12 and the inner wall 16 of said receiving re cesses.

The folded positions of the sections 13 and 1% with the outrigger 12 in the recess 11 is best illustrated in Fig. 4 of the draw ings, the spring catch 19 being provided for each hinge 15 whereby the sections 13 and 1-1 are automatically locked in longitudinal alinement when outstretched.

Cords 20 and 21 are connected between the opposite ends of the Outriggers 12 and the bow and stern of the hull 10 respectively, a pulling upon said cords 20 and 21 serving to outwardly move the outrigger 12 when the same is positioned within its recess 11, such movement being suiiicient to permit such other means as a pole or oar to be used for forcing the outrigger 12 to its operative position with the connector sections 13 and 1 1 open as illustrated in Fig. 1. When in such a position, the cords 20 and 21 will. be held in any suitable manner to maintain the outrigger 12 against longitudinal movement. l/Vhenever desired to fold the sections 13 and 1%, the catches 19 may be released by means of pins 22 carried thereby.

' Adjustable keel sections 23 substantially triangular in cross section are hinged to the central rib or keel 24E of the hull 10, the keel sections being positioned outwardly and disconnected when not in use as indi cated by dotted lines in Fig. 3 of the drawing. The outrigger 12 and keel section 23 upon corresponding sides of the hull 10 are connected together by lines or cords 25 to said hull when the lite boat is positioned for use upon the deck of a vessel, the memhers 23 are outstretched beneath the hull 10 as indicated at one side of the hull in Fig. 3 of the drawings, the keel members 23 serving as positioning struts for the hull when not in use. Upon elevating the hull 10 above. the deck of the ship, the keel members 23 automatically close into contact with each other, latch 26 upon one keel section automatically engaging a keeper perforation 27 through the other keel section and automatically locking the keel sections together in their operative positions. The subsequent outward movement of the outriggers 12 then brings the lines 25 taut and braces the Outriggers 12by means of their connection with the keel sections 23.

Suitable oil tanks 28 are provided adj acent the gunwale 29 of the hull 10 having conduits 30 communicating with the outlet pipes 31 within the recesses 11, the floating of oil through the members 31 being regulated by valves 32 in the conduits 30. The discharge oi oil upon the water at the sides of the hull 10 is designer. to render the surface ofthe water smooth to a desirable eX- tent. Suitable seats 33 are provided in the hulllO as well as lockers 3a and 35, a floor member 36 being provided adjacent the bottom thereof, with storage space 37 therebeneath.

A. serviceable lite boat is provided readily positioned for use in time of need, the keel and outrigger members rendering the craft substantially non -'capsizable, and capable oi? maintaining an even keel when traveling through rough water.

What I cl aim as new is Y 1.. A life boat comprising a hull having longitudinal recesses in 7 s opposite siees, elongated Outriggers, positioned within said recesses'when not in use, keel sections centrally hinged to the bottom of the hull and staying lines connected between the outriggers and the adjacent keel sections adap ed for taut positioning when the outriggers are outstretched and the keel sections are lowered duri the use of the invention.

' 2. In combination with a hull having side recesses, float outrigger-s positioned in said recesses when not in use, hinged connections between said Outriggers and the adjacent sides of the hull adapted for automatically locking when in their outstretched positions, keel sections connected to the adjacent outriggers hinged to the keel portion of the hull and automatic locking connections between said keel sections when the keel sections are closed againsteach other for use.

3. A life boat comprising a hull, keel sec tions centrally hinged to the bottom of the hull longitudinally thereof adapted for outstretched positioning supportin ly beneath the hull when the boat is not in use and latch connections between the hull sections adapted for automatically locking upon the swinging of the keel sections together, in their operative depending position.
